I yanked up all the orange fulva I planted earlier in the summer with the intent of putting in some closeout selections that just came in this week. Is it too late to plant new plants? If so, where should these 4 dozen new guys overwinter? I'm zone 8b in Louisiana and all these guys are going to be full sun.

For me, it's always "best to get them planted in ground"; and "the sooner the better". Then during warm periods of winter and spring, the roots will still grow. But the worst killer for mine is thaw-heaving. If I don't give them a really heavy mulch right after planting, then during one of those warm spells they actually come up out of the ground, exposing the roots and killing them. Whereas, if I mulch them heavily with straw that first winter, they generally survive.

. . . it's always better to ask questions, than jump to conclusions.
AND . . . always hear both sides of the story before making a judgment.

Sorry, I was speaking about daylilies. Brecks had a box of a dozen mixed plants, all pretty impressive, for $19.95. I couldn't pass that up bc, honestly, Brecks plants, whoever they source them from, grow better than any of the more daylily specific nurseries I've ordered from so far in my young daylily habit.

I have enough space to pot but won't unless necessary. Yeah, no frost to worry about here. Yesterday it was 80 but today its probably only going to hit 60.

I am not sure there is a date in zone 8b that is too late to plant new plants. I have never planted any past October, but I really think that you could plant your new plants and mulch around them and they would be fine. I would hate to tell you that and they not make it. Hoping someone who has planted late can give actual experience of such late planting. When I first started out with daylilies I would have been totally against it, but now I seem to push planting a little further back each year, and October is currently my favorite time of year. But November has been so pleasant so far this year, that if I had any plants that needed planting I would have certainly been planting them up to this point.
However, I did see the first freeze warnings for the year(not here) but getting pretty close. I would also love to hear from people who have planted daylilies just before a freeze, how did they do over the winter?

Last year, I planted an order from Maryott's in October- got a bloom in November and every plant made it this spring,- only one variety didn't bloom this year.. I watered them in well, let fall leaves collect and let them alone. (Zone 5b)

Most of my earlier daylilies came from Brecks, Springhill, Michigan Bulb and Gilbert Wild and they all did well. A few were incorrectly labeled, thus some noids. Now that I am no longer a pushover, I want what I paid for
